I've bought it on vodaphone so need it unlocked to enable 3uk.
Do I have to unlock the phone first (using eBay to get a code) or if I flash a custom rom will this unlock the phone?
That aside, to get jelly bean on my g300 do I need to root the phone first and then just flash a custom jelly bean rom and go from the basic stock software straight to the custom jelly bean rom? Or do I need to update the rom first?
Sorry if I'm asking simple questions but I'd appreciate any help.
